The two basic components of a Thevenin equivalent ac circuit are

A small and medium enterprise imports two components A and B from Taiwan and China respectively and assembles them with other components to form a toy. Components A contributes to 10% of production cost while components B contributes to 20% of production cost. Usually the company sells this toy at 20% above the production cost. Due to increase in the raw material and labour cost in both the countries ,component A became 20% costlier and components B became 40% costlier. Owing to these reasons the company increased its selling price by 15%. Considering that cost of other components does not change. What will be the profit percentage if the toy is sold at the new price?

A

15.5%

B

25.5%

C

35.5%

D

40%

While computing the Thevenin equivalent resistance and the Thevenin equivalent voltage, which of the following steps are undertaken?

A

Both the dependent and independent voltage sources are short-circuited and both the dependent and independent current sources are open-circuited

B

Both the dependent and independent voltage sources are open-circuited and both the dependent and independent current sources are short-circuited

C

The dependent voltage source is short-circuited keeping the independent voltage source untouched and the dependent current source is open-circuited keeping the independent current source untouched

D

The dependent voltage source is open-circuited keeping the independent voltage source untouched and the dependent current source is short-circuited keeping the independent current source untouched
